Description
11, 13-16 NC
No connection.
1–4
VX1–4
High Impedance Inputs to Supply Fault Detectors. Fault thresholds can be set from 0.573 V to 1.375 V.
Alternatively, these pins can be used as general-purpose digital inputs.
5–7
VP1–3
Low Voltage Inputs to Supply Fault Detectors. Three input ranges can be set by altering the input attenuation
on a potential divider connected to these pins, the output of which connects to a supply fault detector. These
pins allow thresholds from 2.5 V to 6.0 V, 1.25 V to 3.00 V, and 0.573 V to 1.375 V.
8
VH
High Voltage Input to Supply Fault Detectors. Three input ranges can be set by altering the input attenuation
on a potential divider connected to this pin, the output of which connects to a supply fault detector. This pin
allows thresholds from 6.0 V to 14.4 V and 2.5 V to 6.0 V.
9
AGND
Ground Return for Input Attenuators.
10
REFGND
Ground Return for On-Chip Reference Circuits.
12
REFOUT
2.048 V Reference Output.
17-24
PDO8–1
Programmable Output Drivers.
25
PDOGND
Ground Return for Output Drivers.
26
VCCP
Central Charge-Pump Voltage of 5.25 V. A reservoir capacitor must be connected between this pin and GND.
27
A0
Logic Input. This pin sets the seventh bit of the SMBus interface address.
28
A1
Logic Input. This pin sets the sixth bit of the SMBus interface address.
29
SCL
SMBus Clock Pin. Open-drain output requires external resistive pull-up.
30
SDA
SMBus Data I/O Pin. Open-drain output requires external resistive pull-up.
31
VDDCAP
Device Supply Voltage. Linearly regulated from the highest of the VP1–3, VH pins to a typical of 4.75 V.
32
GND
Supply Ground.
